GRAB-POLE.

Specification of Letters Patent.

Application filed January-14, 1916. Serial No. 72,151.

,To all whom-it may concern:

Be it -known that I, FRANK Dnnnrrs, residing in Hoboken, inthe countyof'Hudson and State of New Jersey, have invented a new and ImprovedGrab-Pole, of which the following is a specification.

My invention whichhas referenceto store service appliancesprimarily hasfor its object to provide an economical, neat, easily, operated andeffective appliance in the nature of a grab poleadaptedtoietch down fromhigh shelves, articles such as canned goods, bo ttlesand other packagesusually found in grocery and delicatessen stores, and by the use ofwhich the need of step ladders and thelike for lifting articles fromhigh shelvesis done away with, r

With other objects. in view, that will be explained, my invention is anappliance for the purposes stated that embodies the peculiar featuresof; construction and novel arrangement of parts, hereinafter fullydescribed,.specifical'ly pointed out in the appended claimsand'illustrated in the accompanying drawing, inwhich:

Figure 1 is a perspective view of my ins vention and illustrates themanner of usmg the same. Fig. 2 isa perspective .view of the upper endof the appliance, the grab membersbeing open "as shown in Fig. 3 isasection of the lower portion of the pole. ,Fig. 4 is a vertical sectionof the upper end of the appliance taken practically on Fig. 5 is anelevation of the device, the arms being in the normal or closedposition. Fig. 6" is a detail section of the fulcrum. Fig. '7 is adetail spring.

wooden pole 1, of suitable length, the .upper,

My improved appliance comprises a end of which is capped by a metalferrule or band 2. At the; lower of handle end, the pole 1 has anelongated recess 3, and in the said .recess is pivotally mounted theinner end' of a trigger lever 4.. with which connects a flexible link'5secured on the lower end ()0 of a steel wire pull rod 6, that extends upthrough the pole and has its upper end (31 extended beyond the upper endthereof, the reason for which will presently appear.

7-7 designate a. pair of toggle link memhers'and they are pivotally v connected at Fig. 2.

' their lower ends, to a stud screw 9 that passes into the ferruled endof the polel.

88 designate .a pair of crossed toggle levers I (pivotally connected bya .fulcrum stud 83) whose lower ends are pivotally connected by rivetpivots ,70,70 to theupper ends of the link members 77 which, as also themembers 88, are preferably .formed of stout strap steel. i

vLever members 88 have. their upper ends bent forwardly at right anglesto form grab arms 81-81 andthe said arms, as is clearly shown in Figs. 2and 3, are relatively 8282, when the members 88 are opened or spread, asin Fig. 2, for grabbing an artiole, are n practically parallel relationand in longitudlnal alinement with the pole.

To keep the grab armsfrom slipping off I an article grabbed thereby,=.particularly Patented A r. 25, 1916.

' so bent and projected from their respective members 8-8 so that theirgripping facescans, glass ware and the like rubber sleeves 10 aresecured thereon and to keep the said rubber sleeves from freely slippingoil the i said arms and to further provide for a posi;

tive gripping of the articles theouter endsof the said armsare curveddownwardly so that the gripping tendency of the said arms is such as toclose around the article.

The upperend 61 of the nates in a loop 62 adapte slipped over thefulcrum stud 83 andby reason thereof it is obvious that when the triggerlever is pulled down the. several le ver members spread to the positionshown in Fig. 2.

11 designates a' stout bow spring, one end the upper end of the pole inwhich it is held clamped by the ferrule 2, as is clearly shown providedull wire termi to .be readily,

77 and 8 -8 are opened or with a notch-like seat 13 that ex .of whichprojects down into a socket 12 on tends under and interlocks with thefulcrum stud 83. By reason-of providing a bow spring device and mountingit on the end of the pole, as shown and described, the said memberbeside serving as the spring. device that normally tends to close thegrab arms, also serves. as a stay or support for the toggle leverdevices and keeps 'them in a positive rigid relation as they are movedtothe open positionby manipulating the tugger lever 4 and moved totheir, closed position by the said spring 11. Again, by rea' son ofproviding a spring device, as shown, a stout spring tension is at alltimes on the grab arms to hold them positively closed on the articlegrabbed thereby, and in case the spring should break, a new springmember can be readily substituted.

From the foregoing description taken in connection with the drawing, theconstrue tion, the manner of use and the advantages of my invention willbe readily apparent.

What I claim is: 1. In an appliance of the character described, thecombination with a pole, a pair 151' of link members piyotally connectedat their lower ends on a common pivot to the upper end of the pole, apair of crossed toggle 1evers pivotally connected at their lower ends tothe free ends of the link members, a stud pivot that joins the crossedtoggle levers, a spring device secured at one end to the pole and at theother end to the stud pivot on the crossed toggle levers that tends tonormally move the toggle levers to their closing posi- 2a tion, theupper ends of the crossed toggle levers being bent at right angles toform grab arms, and a liezrible pull that connects with the iulcrumpivot for the crossed toggle lei aid pull including a portion that extlawn to the handle end of the pole.

I an appliance of the character dethe combination with a pole, a pair alinks pivotally connected at their to a single stud pivot on the pole,,rossed toggle levers pivotally contheir lower ends to the upper endsgle links that are attached to the stud pivot that forms the fulcrum acrossed levers, said crossed levers their upper ends bent at rightangles :1 a pair of opposing grab members,

a bun spring having an end secured to the impel end of the pole and itsother end notched to slip into locked engagement with at the stud pivotand a flexible pulling element that connects at the upper end with thefulcrum stud pivot and whose lower end extends down to the handle end ofthe pole.

3. In an appliance of the character described, the combination with apole, a pair of toggle links pivotally connected at their lower ends toa single stud pivot on the pole, a pair of crossed toggle leverspivotally con nected at their lower ends to the upper ends of the togglelinks that are attached to the pole, a stud pivot that forms the fulcrumfor the crossed levers, said crossed levers having their upper ends bentat right angles to form a pair of opposing grab members, a bow springhaving an end secured to the upper end of the pole and its other endnotched to slip into locked engagement with the stud pivot and aflexible pulling element that connects at the upper end with the fulcrumstud pivot and whose lowerend extends down to the handle end of thepole, a trigger lever pivotally mounted in the said handle end of thepole and a flexible connec tion that joins the trigger lever with thesaid pull member.

4. An appliance for the purpose described comprising a pole, togglelevers pivotally mounted on the upper end of the pole, said leversincluding crossed members having portions bent at right angles to formgrab arms, a stud pivot that forms the fulcrum for the crossed members,a bow spring prog'gcted from the upper end of the pole and having itsupper end interlocked with the stud pivot, and a flexible pull memberthat extends to the lower end of the pole and has its upper endconnected with the pivot stud, all being arranged whereby by drawing onthe pull member the levers are extended to open the grab jaws the" saidbow spring tending to normally move and apply tension to the bow spring,

the toggle levers and the grab arms to the crossed or grabbing position.
